Title: Mechanism and method for converting a fixed wheel walk-behind mower to a caster walk-behind mower and vice versa
Inventor: BOWDITCH HOEL L
IPC: A01D34/74
Filed: 1988-08-26
Granted: 1992-06-16
Abstract: ABSTRACT   A mechanism and a method for converting a fixed wheeled walk-behind mower into a caster wheel walk-behind mower and vice versa comprising two caster wheel assemblies having wheels mounted in brackets journalled for rotation in frames.  Each frame has means for attaching the mechanism to the front wheel axle.  Each caster wheel assembly comprises an elongated member connected to each frame and extending the length of the mower on each side between the frame and the respective rear wheel axle or mower housing.  At the end of the elongated member most remote from its connection to each of the ' frames, a U-shaped notch is formed therein for connection with the housing. tie rod is provided for interconnecting the two frames, for adding rigidity to the assembly and for maintaining the correct, constant distance between the frames.  The mechanism can be rapidly converted between castering and a conventional walk-behind mower with fixed direction wheels with the only modification being the forming of a groove in the rear axle proximate each rear wheel.

Title: Mine hoist brake regulator

Granted: 1992-07-28
Abstract: Case 3007 MINE HOIST BRAKE REGULATOR ABSTRACT OF THE DISCLOSURE           There is described a hydraulic friction brake for controlling deceleration of a mine hoist which brake includes a pump continually circulating hydraulic braking fluid through a valve.  The valve regulates the flow of hydraulic fluid to control braking pressure applied by the brake to brake the mine hoist.  The hydraulic friction brake includes a controller for controlling operation of the valve.  The controller a comparator for comparing a differentiated signal indicative of hoist speed with the reference signal indicative of a predetermined hoist deceleration to provide a switching output signal having a first output value when the differentiated signal is greater than the reference signal and having a second value when the differentiated signal is less than or equal to the reference signal.  The control means also includes an integrator responsive to the output signal to provide a first valve signal that controls the operation of the valve.  By integrating the switching output signal it is possible to provide a valve control signal that opens the valve at a rate predetermined and thereby reduce the braking pressure of the brake in proportion to the deceleration of the hoist.  Further, when the output signal is indicative of a maximum allowable deceleration rate for the hoist, the integrator provides a constant output signal which maintains the opening of the valve constant.  As a result a maximum braking acceleration for the hoist is not exceeded.

Abstract: The invention relates to a method for measuring wear in the lining of a container provided with a pivoted axle and an opening, and a container. Fixing of the coordinate systems (16, 17) of a measuring device (1) and the container (6) is performed by measuring the position of fixing points (P1, P2, P3) in the coordinate system (16) of the measuring device, whereafter the lining (10) on the inner surface of the container (6) is measured. The fixing is performed by measuring the position of the fixing points (P1, P2, P3) mounted in connection with the container in the coordinate system (16) of the measuring device (1) in a situation where the opening of the container faces away from the measuring device while the measuring device is directed towards the container bottom. The container (6) is rotated around its pivoted axle (11) to a position in which the opening (9) of the container (6) faces the measuring device (1). The fixing is performed utilizing the angle difference between angle data ( alpha 1) obtained during the measurement of the fixing points (P1, P2, P3) and angle data ( alpha 2) obtained after the rotation of the container (6), said angle difference being obtained by angle measurement known per se, measuring the inclination of the container (6). <IMAGE>

Abstract: Method and device for controlling a beam of light (17), which is coupled in into a working layer (2) of electro-optical material and which is supplied to a working area (16). In a first optically conductive state the working area has a poling mode which differs from the one of the surrounding working-layer material (7), as a consequence of which other refractive indices will arise, due to which the working area will form a light waveguide through which the beam of light coupled in will be conducted (19) to a first glass fibre (22). In a second optically conductive state the working area has a poling mode whioh is equal to the one of its surroundings. Because of the fact that the refractive indices inside and outside the working area are now equal, the working area will not form a light waveguide, but (e.g.) a light insulator or a light reflector, by means of which the beam of light coupled in will be conducted to a second glass fibre (21). The quasi-stationary poling mode of the working area required for the first respectively the second optically conductive state will be reached by successively - warming up the working area to above the softening temperature, - exciting an electric field in the working area, and - letting the working area cool down again. For poling the electric field has a value unequal to 0; for unpoling a value equal to 0.
